Spam Links??

Hello webmasters, this time i want to know that how i come to know our spam Links? We do all off page activities as same as we did but still keywords get down from there current position. Is it happen due to spam links? How we can check where we did spam?

Is this something that has happened suddenly (in which case it may just reverse itself without you doing anything) or over a period of time?
Either way it is unlikely that the problem is due to spam linking, but (unless a competitor is doing it to you) I would have thought you would have known where your links are coming from anyway? You can view every link that Google has found in webmaster tools.

I think it is more likely that if you have being doing the same as always your competitors are doing something different that has allowed them to overtake you.

There are so many possible reasons for a site to drop down in the rankings, and perhaps it would help if you would give the site name and the keywords that are affected.

Hi,
I agreed. There are several reasons of drop in the keyword ranking. Only spam links are not the reason.
Analyze your strategy and improve the content of your website. I think, this will help you to have a lift in the keywords.
